My sisters and I were all born in December, mine was the latest on Dec 21. My parents were very keen on making sure that we all got the same number of presents for our birthdays. I sometimes got combined birthday/Christmas present but it would be a special gift. The one thing I missed out growing up was being able to celebrate my birthday during the school day, as we were always on Christmas break. In my own family (husband and two kids), we all are born in a different season, daughter in spring (May), son in summer (July) and husband in fall (Oct). Nicely spread out throughout the year :)
